How do I write radian decimals in terms of Pi?

[jester0608]

How would i write 1.047 rad in terms of pi? I know the answer i will get is Pi/3 rad, but HOW do i get this answer? I know how to convert degrees to radians and vice versa in terms of pi but this particular question is in radians. Help?

1.047/pi≈1/3
1/3*pi=pi/3

1.047/pi≈1/3
1/3*pi=pi/3

But when I calculate 1.047 / pi I get 0.33327. How did you get 1.047/pi ≈ 1/3 ? that's the only part i don't understand

Since your result 1.047 is written with 4 significant figures, you ought to keep that many in $\theta = \pi / x \Rightarrow x =\pi / \theta = 3.001$.
